Ethernet PHY transceivers

Microchip Technology, Inc. announced the availability of KSZ8061, a single-chip 10BASE-T/100BASE-TX automotive and industrial grade Ethernet physical layer transceiver, designed for data communication over low-cost UTP cables. It is the first of a new family based on the patented and programmable Quiet-WIRE® enhanced EMC technology, providing reduced line emissions and superior receiver immunity performance. System reliability is also enhanced with Microchip’s proven LinkMD+^® advanced cable diagnostics, along with an embedded signal-quality indicator for the dynamic monitoring of link error margins.  

“The KSZ8061 provides uniquely low emissions and high immunity over unshielded cabling, for automotive and industrial Ethernet network connectivity,” said Mitch Obolsky, vice president of Microchip’s USB and Networking Group. “The result is a significant reduction in BOM costs, versus expensive shielded cables, while meeting the stringent EMC specifications for these applications. Additionally, the established Ethernet ecosystem provides a low total cost of ownership and multifaceted benefits.”  

With fast boot and linkup in less than 20 mS, the KSZ8061 is ideal for applications where startup time is critical, such as automotive rearview cameras. The KSZ8061 family is available with an extended temperature range of -40 to +105 degrees Celsius for harsh-environment applications, including industrial sensor networks, robotics, building automation and avionics. This Ethernet PHY transceiver family provides support for both the MII and RMII processor interfaces, for easy integration with numerous processors, MCUs and SoCs.
